Claude adds skill and plugin security scanning for Enterprise the same day Agent Plugins ships
Anthropic Release Notes·medium signal
Claude's release notes for August 6, 2026 add "Skill and plugin security scanning (beta)" for Enterprise plans, checking third-party skills and plugins for malicious content. The timing is the story: it lands the same day the Agent Plugins 1.0.0 standard makes skill and MCP bundles freely portable across ChatGPT, Codex, Cursor, Copilot, Kiro, and VS Code — a distribution surface that did not exist a week ago. Single-source (first-party release note) with no accompanying blog post detailing the scanner's method.
